Gmail – Does Email Storage Calculate Per Plus Sign or Alias Address?

gmailgmail-filters

With Gmail you can arrange additional address aliases by appending + and any arbitrary string to your original login.

Example:

  • original account: johndoe@gmail.com
  • sample aliases: johndoe+subscriptions@gmail.com, johndoe+work@gmail.com, etc.

Do messages sent to an alias address add up to the original account's storage limit,
or by working with aliases can one get some additional storage, say: 2GB per alias?

Best Answer

Alias = mirror of the original or main email address. Therefore the disk space is shared between the two.

Good explanation over here.

An alias is essentially just a nickname for a mail account. The alias itself has no mailbox and all mail sent to it will be delivered to the mailbox it is mapped to.
